AUTOMATIC TENSION-WIRE AND BOBBIN-BRAKE FOR WARPERS.

SPECIFICATION forming part of Letters Patent N o. 624,695, dated. May 9, 1899.

Application filed September 29, 1898. Serial No. 692,219. (No model.) d

To all wtom t may concern:

Be it known that I, THOMAS HENRY SMITH, a citizen of the United States, and a resident of Jamestown, in the county of Chautauqua and State of New York, have invented a new and useful Automatic Tension-Wire and Bobbin-Brake for Warpers, of which the follow-A .ing is a specification.

The object of my invention is to make an inexpensive and efficient automatic tension- Wire or take-up and brake for warpfbobbins which will regulate the tension of the yarn-or thread and prevent slack yarn from the bobbins running onto a warpers mill or creel; and my device consists of a bent-wire bridle having a weight or brake-shoe thereon hung from the Creel-standards at each end and in front of each bobbin and resting upon the thread or end as it runs off the bobbin, as shown in the accompanying drawings, in which- Figure 1 is a perspective view of my automatic tension-wire and bobbin-brake. Fig. 2 is a side elevation of a section of a warpers creel, showing my device in different positions caused by the running of the threads. Fig. 3 is a front perspective view of the upper corner of a warpers creel, the remainder being broken away and my device attached to each bobbin,

Similar numerals refer to similar parts in the drawings.

10 represents my tension-wire or bridle,

which has eyes 11' 11 bent at the ends to.

receive pins or nails 11 11 for hinging the bridle to the creci-standards 13 13 at each end of the bobbin l5, which allows the wire 10 to swing loosely as it rests on thread or running end 16. 'Bobbins 15 l5 run on Creel-.pegs in holes 18 18 in standards 13 13. From one of the eyes 1l' I bend the wire back in arm 12 and out at about al right angle thereto in brake-Enger 14 and attach brake-shoe 14! to brake-iinger 14. Brake-shoe 14' is made of metal or any substance which will give the proper amount of drag on the bobbin-head, and the form of the brake-shoe may be round or square; but I prefer it round'and of considerable weight, since the weight adds to the tension of the bridle on the thread and gives` a much greater drag on the bobbinhead. The metal is durable, and the round form does not scrape on the wooden bobbin-head, but rides smoothly. It is ofcourse linderstood that this evil of slack or lashing threads takes the time of the warper and spoils the warp. My simple and automatic device prevents this and runs the threads all on the warp-mill at one even tension. If the thread runs slack, the falling wire follows it and takes up the slack and prevents its running onto the warp mill or beam or from lashingI into the next end and being carried thereby onto the mill or beam, and should this slackness be more than the falling wire will take up brake-shoe 14 falls on the bobbin-head and slows up the motion of the bobbin until the thread is brought to an even draw again. Y

Imperfect winding of the bobbins and other causes vary the speeds of the bobbins, and the positions of the wires 10 10 are constantly changing to different angles up and down, as`

shown in Figs. 2 and 3. It will be noticed that I take the thread from the upper side of the bobbin instead of from the under side, as is often done, and that this change simplifies the whole process and my device for regulating the tension, allowing a direct weight, which can also be used as a brake-shoe.

I claim as new-n An automatic tension or take-up and b0bbin-brake for a warpers creel having a wire bent to'form a bridle to ride on the unwinding end of the thread, saidbridle hinged to the Creel-standards at each end to swing free in front of the bobbin, said wire bent to form a brake-inger, aweight or brake-shoe on said.

In witness-that I claim the foregoing I herev unto subscribe my name in the presence of two witnesses. v

THOS HY. SMITH.
